Fumble advance 5yds?

1st-10, DAL48 15:00 J. Kitna sacked by W. Smith. J. Kitna fumbled. M. Bennett recovered fumble and returned for 5 yards

Bennet should have been down by contact. Instead they were given a 2nd and 5.
even tho i understand where you are coming from, we didnt say these things about hargrove in the carolina game last year when he scooped up a fumble being touched from every area. he got up and walked into the enzone. just trying to be fair
